TILT SENSOR

Description

INFOID:0000000009720735

• The tilt sensor is installed to the steering column assembly. 
• The pulse signal is inputted to the driver seat control unit when the tilt is operated.
• The driver seat control unit counts the pulse and calculates the tilt amount of the steering column. 

Component Function Check

INFOID:0000000009720736

1.

CHECK FUNCTION

1.

Select “TILT PULSE” in “Data monitor” mode with CONSULT.

2.
